The MOV-14D390KTR is a Varistor, or Metal-Oxide Varistor, MOV, that has both a wide range of applications and a simple working principle. This particular MOV-14D390KTR is a radial-leaded component primarily used in AC line filtering and AC line circuit protection, and offers high energy and a wide voltage range tolerance.

Varistors are designed to protect circuits from over-voltage and transient voltages, allowing current to bypass the circuit when the voltage rises beyond acceptable levels by getting in the way. MOVs, which are essentially just a kind of Varistor, provide higher energy ratings while allowing for faster surge response and wider voltage range tolerance. This makes them a more robust protection solution for delicate electronic equipment.

The MOV-14D390KTR consists of a zinc-oxide element layered between two metal plates. The element is connected to terminals that are then connected to external circuit boards, with the metal plates acting as a shield. These elements are designed to trigger or deactivate when the voltage surpasses the pre-set threshold. When this happens, the MOV-14D390KTR will quickly change from a high-impedance open circuit to a low-impedance path, allowing the current to bypass the circuit.

The MOV-14D390KTR has a wide range of applications. It is primarily used in over-voltage and transient-voltage circuit protection, AC line filtering, and noise suppression. It is also commonly used in switch-mode power supplies, adjustable speed motor drives, computer peripherals, electronic lighting, and medical equipment. The versatility of the MOV-14D390KTR makes it suitable for use in a variety of applications, from commercial and industrial to military and automotive.

In addition to superior protection against over-voltage and transient-voltage, the MOV-14D390KTR has excellent thermal stability, making it suitable for use in extreme temperatures. It also has excellent surge-current and clamping capabilities, making it one of the most reliable Varistors on the market. The MOV-14D390KTR is a UL and TÜV certified MOV and meets both the UL 1449-15 standard and EN 61000-4-5 standard.

The MOV-14D390KTR is designed for superior protection in AC line circuits, AC line filtering, and in the suppression of noise and over-voltage.
